A paper from the research group of electrical & computer engineering professor Zhen Peng has been selected as the 2023 Richard B. Schulz Honorable Mention Transaction Paper. It was chosen by the editorial board of the IEEE Transactions on Electromagnetic Compatibility from 208 papers published in 2023.
The paper, cowritten with postdoctoral research associate Shen Lin and graduate student Sangrui Luo, presents a new methodology for modelling the behavior of electromagnetic waves enclosed in a finite space.
“This is a problem that comes up for any kind of confined electromagnetic systems, such as electronic enclosures and indoor wireless communications,” Peng said. “However, it has proven exceptionally difficult to study because the enclosure makes the waves chaotic, making computational studies with standard methods intractable.
The waves reflect and scatter from the enclosure’s surfaces so often that their features essentially become randomized, making it difficult to understand how they interact with antennas, electronics and other objects in the enclosure.
“We approach the problem by proposing a mathematical tool called the stochastic Green’s function, a statistical substitute for Maxwell’s fundamental field theory that is still physics oriented,” Peng explained. “It resolves the vectorial nature of the wave more rigorously than other statistical approaches, and we have even advanced the technique to resolve variations in space and time. This has important implications for indoor information transmission, wave shaping and focusing, sensing, targeting and many other applications
Peng’s other collaborators include Illinois ECE teaching professor Yang Victoria Shao; University of Maryland, College Park professors Steven Anlage and Thomas Antonsen; and U.S. Naval Research Laboratory researchers Bisrat Addissie and Zachary Drikas.
The award will be presented at the 2024 IEEE International Symposium on Electromagnetic Compatibility, Signal & Power Integrity in Phoenix.
The paper, “Predicting Statistical Wave Physics in Complex Enclosures: A Stochastic Dyadic Green’s Function Approach,” is available online. DOI: 10.1109/TEMC.2023.3234912
